Those tiny bugs in your mealworm farm are grain mites. They are a common problem and can difficult to get rid of. People have tried all sorts of things to remove these bugs, but not all work. Based on my experience, the following are the best ways to remove and prevent grain mites from infesting your farm.
Grain mites are drawn to mealworm farms if there is too much moisture, waste and poor ventilation. Infested mealworm farms have to be thoroughly cleaned and disinfected to avoid further spreading.
What Attracts Grain Mites to a Mealworm Farm?
Mealworms play an important part in the natural ecosystem. In the wild it’s normal for them to draw the attention of other bugs.
One of those bugs are grain mites. Like mealworms, grain mites also feed on grains and organic matter. So it comes as no surprise that they would find environments like mealworm farms appealing.
But not all mealworm farms get infested by grain mites. So if yours is afflicted, what could be the reason? There are several possibilities why those tiny bugs may be present in your mealworm farm:
Accumulation of organic matter. Mealworms produce frass (waste), which accumulates in the bedding. This frass serves as a food source for grain mites. If the waste is not properly disposed of, mites will be draw to it and reproduce. It won’t be long before they proliferate.
High Moisture levels. Grain mites require a humid environment to thrive. If the moisture levels in your mealworm farm are too high, it creates an ideal environment for these mites to reproduce. Very moist bedding can lead to the growth of mold or fungus which attracts more mites.
Poor air circulation. A lack of airflow in a mealworm farm can contribute to high humidity levels. Insufficient ventilation prevents the moisture from escaping, creating an environment conducive to mite infestations.
That is an overview of what causes grain mites and other bugs to infest a mealworm farm. Now let us look at each in detail.
How to Get Rid of Grain Mites in Mealworm Farms
Getting rid of grain mites in a mealworm farm can be a challenging task, but with proper measures and attention, it is certainly manageable. Here’s a step-by-step guide that will help you eliminate grain mites and prevent them from infesting your mealworm farm.
Identify the Problem
Grain mites are tiny pests that thrive in warm and humid environments. They usually infest grains, flour, and stored food products, making them a common nuisance for mealworm farms. Look for signs of grain mite infestation, such as small brown or reddish-brown specks on the mealworm bedding or a foul odor.
Isolate Infested Containers
If you notice grain mites in your mealworm farm, act promptly to prevent their spread. Isolate any containers with signs of infestation from the rest of the farm. This will help contain the mites and prevent them from infesting the entire colony.
Clean and Sanitize
Thoroughly clean and sanitize the mealworm farming area to eliminate any potential breeding grounds for grain mites. Remove all bedding, old food, and any contaminated substrates.
Disinfect the containers, farming equipment, and the surrounding area using a mild bleach solution or insecticide approved for use in mealworm farming. Make sure to rinse and dry everything properly before reintroducing the mealworms.
Reduce Moisture Levels
Grain mites thrive in high humidity conditions, so it’s crucial to maintain dry and well-ventilated conditions in your mealworm farm. Ensure proper airflow by using a fine mesh or ventilation holes on the containers to avoid excessive moisture buildup. Avoid overwatering the bedding and keep it slightly dry to discourage mite infestation.
Proper Storage of Food
To prevent grain mites from finding their way into your mealworm farm, practice proper storage of food items. Keep all grains, flours, and other food sources in airtight containers somewhere separate from the mealworm farm. Regularly inspect the storage area for signs of infestation and dispose of any infested items immediately.
Pest Control Measures
To get rid of grain mites in your mealworm farm, you can use natural pest control methods. Some effective options include:
Diatomaceous earth: Sprinkle a thin layer of food-grade diatomaceous earth on the mealworm bedding and surrounding areas. This natural substance damages the mites’ exoskeleton, dehydrating and ultimately killing them.
Beneficial predators: Introduce beneficial predators like predatory mites or beetles that feed on grain mites into the mealworm farm. These predators will help control the mite population by feeding on them.
Monitor and Repeat
Regularly inspect your mealworm farm for any signs of grain mite reinfestation. If you notice any, repeat the cleaning and pest control measures mentioned above until the infestation is completely eradicated. Stay vigilant and maintain good farm hygiene to prevent future infestations.
How to Keep Grain Mites Away from Mealworm Farms
The only thing better than getting rid of grain mites is making sure they never come back. Follow these steps to keep grain mites away. If you have a new mealworm farm, you can follow these tips too.

Regular cleaning and maintenance. Clean out the bedding regularly, removing excess frass and decaying food. Replace the substrate to prevent the buildup of organic matter that attracts mites.
Manage moisture levels. Ensure that the moisture levels in the bedding are optimal. If it is too humid, consider reducing the moisture by using a more absorbent bedding material, such as bran or oats. Avoid overwatering or adding too much fresh fruit or vegetable matter to the farm.
Improve ventilation. Provide adequate airflow by placing air vents or holes in the mealworm farm to maintain a well-ventilated environment. This will help in controlling the humidity levels and discourage mite growth.
Monitor and isolate. Regularly monitor your mealworm farm for signs of mite infestation. If you notice an excessive number of mites, consider temporarily isolating infected mealworms and replacing the bedding to disrupt the mite population cycle.
Remember, grain mites are harmless to humans and mealworms. By implementing proper hygiene, moisture control, ventilation, and regular monitoring, you can effectively manage the presence of tiny bugs in your mealworm farm and ensure a healthy and thriving colony of mealworms.
Can Grain Mites Harm You?
Grain mites are generally harmless to humans. They do not bite, sting, or cause any direct harm to our bodies. However, their presence in food products can pose risks in some cases. Here are a few factors to consider:
Allergies. Grain mites produce tiny particles such as feces and shed skin, which can trigger allergic reactions in some individuals. These reactions may manifest as respiratory symptoms like sneezing, runny nose, coughing, or itchy eyes. People with existing respiratory conditions or allergies may be more susceptible to these effects.
Contamination. Grain mites can contaminate stored food products by their presence alone or through their waste products. In large quantities, they can impart an off-putting taste and odor to the affected food. Although consuming contaminated food does not usually pose a serious health risk, it might cause gastrointestinal discomfort or allergic reactions in sensitive individuals.
Secondary contamination. Grain mites can attract other pests such as mites, beetles, or weevils, which can cause further damage to stored grains. These secondary pests can also contaminate the food, potentially leading to a decrease in its nutritional value and quality.
To minimize the risk of grain mite infestations and their potential harm, it is important to practice good hygiene and food storage practices. Here are a few preventive measures:
- Store food properly. Keep grains, cereals, and other susceptible food items in airtight containers to prevent mite infestations. Regularly check the packaging for any signs of damage or openings that could allow mites to enter.
- Rotate stored food. Use the “first in, first out” principle when storing food. Consume older food items first to ensure they are fresh and not infested.
- Clean storage areas. Regularly clean storage areas and shelves to remove any potential sources of infestation, such as spilled grains or food residue.
- Maintain proper humidity levels. Grain mites thrive in humid environments. Monitoring and controlling humidity levels in storage areas can help reduce the risk of infestation.
Conclusion
So aside from mealworm farms, grain mites can pop up in other food sources. But if you follow the steps here, that can be avoided.
Ultimately, while grain mites are generally not harmful to humans, their presence can lead to contamination and potential allergic reactions. It is advisable to take precautions to prevent infestations and maintain the quality of stored food products.
